It was Dallas' defense, plain and simple! Ask LeBron and Wade. Every commentator said how well Dallas kept them out of the paint. Jason Kidd's, Marion, Tyson, and even Dirk play tremendous D. I can remember who said it but they said that Iguadala, PP, and Deng tried to take it personally and tried to stop LeBron on their own but Dallas played better team defense on him... I totally agree!!!
